An error occurred registering the form in the OLE registry

[Guest]

I have a few users that cannot display Outlook forms. They get the following
Outlook error: "An error occurred registering the form in the OLE registry."

Once they try to access the forms and get this error, Outlook will always
hang on the application shutdown.

The Custom Form is published in Public Folder; These machines are all
running on Windows Xp Professional SP1 with MS Office XP. When these users
are set as Power User, they cannot display any form. When they are set as
Administrator, they can display forms.

I have deleted the frmcache.dat file, but i can't delete the Usrclass.dat.
The error is "The process cannot access the file because it is being used by
another process"
and the problem it persists
http://support.microsoft.com/default.aspx?scid=kb;en-us;320835

any idea???

Thank's

I'm not sure which app could have a lock on usrclass.dat, so shut down
everything and try deleting it again. Also try deleting after a fresh boot,
or in Safe Mode.

I was logged with user and the usrclass.dat in C:\Documents and
Settings\User\Local Settings\Application
Data\Microsoft\Windows was locked by System Process.
For rename the file, I've had logout with user account and use an
administrator account to log in the computer. With this mode, the file
usrclass isn't locked by System Process.

Thanks
